Background

With the development of the industry in China, a large number of high-rise tower devices exist in the petrochemical industry, the high-rise tower devices have the characteristic of high flexibility due to the structural characteristics of the high-rise tower devices and are sensitive to wind loads, in the actual wind load bearing process, transverse wind direction vibration, namely wind induced vibration, is often much larger than downwind direction vibration, so that the vibration of a tower body is frequent, fatigue cracks are easily generated at the connecting parts of the tower body structure and a base due to the fact that the tower body structure and the base bear fatigue loads for a long time, hidden dangers are brought to the structural integrity of the tower body, and the problem of how to solve the vibration reduction of the high-rise tower devices is always paid much attention.

The damping principle of Tuned Liquid Dampers (TLDs) is that an external excitation causes a structure to vibrate, thereby driving the TLD to move. Through the shaking of the liquid in the box body of the TLD vibration damping device, the energy of the vibration of the main structure is dissipated by the friction force generated by the shaking of the liquid in the box body of the boundary layer TLD vibration damping device and the broken waves generated under strong excitation, so that the vibration of the main structure is reduced.
